It is bordered to the south by the edge of the towns of Exmouth and Budleigh Salterton, the hamlet of Yettington to the east, and the A3052 to the north.
The heathland has wide swathes of gorse and heather (bell, cross-leaved and ling varieties) and is a popular spot for orienteering, hill-walking, mountain biking and flying radio-controlled aircraft.
Reinforcements in the form of Italian mercenaries and German Landsknechts under the command of Lord William Grey arrived on 2 August to assist the king's troops under John Russell, 1st Earl of Bedford., who was charged with defeating a large force of rebelling men from Cornwall and Devon.
[3] The next day, the king's army of some 5,000 men began a march from Honiton to relieve Exeter, which was under siege at the time, but instead of taking the heavily barricaded highway, Russell went westward, across the downs.
There were heavy losses on both sides and the result was inconclusive but Russell's army took many prisoners, 900 of whom were executed the next day in the Clyst Heath massacre.
